8 Claims.

This invention relates generally to containers formed preferably of fibrous sheet materials and particularly to such containers constructed with a plurality of plies of sheet material formed in a cylindrical or other desired shape. In its widest purview, the invention includes combinations of sheet metal and fiber board united by stitching or stapling to provide a strong and economical type of container, but the invention is more particularly directed to fiber board containers of various shapes, particularly cylindrical shapes, of either one or more plies, where the parts may be economically die-stamped and assembled under modern production methods rapidly and,

cheaply by means of a unique arrangement, and such fiber board containers may be made substantially air and water impervious, and while extremely light, nevertheless, may be made of strong and rigid constructions that are competitive with metal or wood barrels or like containers.

Heretofore, a variety of wood, metal or fiber board containers have been in use or havebeen suggested, but such containers have been com-,

mercially disadvantageous because of either one or several of the following reasons: (1) excessive weight. (2) excessive expense, (3) corrosion of the container, (4) flimsiness,'(5) leakage, (6) difilculty of handling.

Therefore, it is an object of my invention to produce a fiber board container having one or a more plies of sheet material in its walls in such fashion that the parts may be rapidly and easily constructed by simple die-cutting, stamping and forming operations and may be easily assembled.

It is an object of my invention to construct such a class of containers either in cylindrical or other shapes, and to preferably unite the various portions oi. the container by sewing or stapling operations.

It is a further object oi my invention to form such containers of a plurality of sheets of fiber board or the like, and to interleave the edge portions of the plies in such fashion as to minimize the eifects of overlapping parts and preferably to sew various portions of such containers together in order to obtain peculiar assembly economies and to obtain unique strength advantages where the walls are formed in a multiply construction, and also to obtain certain advantages in using the containers.

It is a further object of my invention to utilize sheet metal in combination with fiber board in such class of containers.

It is a further object of my invention to provide a unique head for such class of containers.

It is a further object of my invention to provide a rolling strip for cylindrical containers of such class, thus permitting ease in handling.

It is a further object of my invention to form such containers with a cylindrical body portion, to sew the head'in place, and toproduce and to friction-fit the head in such manner that the same may be depressed downwardly within the cylinder to maintain contact with the goods inside the container, even though portions of the materials originally packed have been removed from the container.

It is a further object of my invention to provide various types of liners for such containers in such fashion that raw edges of the fiber board stock will not come into contact with the goods packed within the container. H

It is a further object of my invention to provide anew and improved closure structure for closing the filling openings of such containers.

It is a further object of my invention to provide sewn multiply containers of the class described, wherein a ribbon of adhesive material is inserted between interleaved marginal portions It is a further object of my invention to provide stitching means for such containers and to also unite various plies of a multiply wall to a minimum extent in their overlying areas, preferably by sewing, in order to attain maximum strength resistance to shock or impact forces, as well as to give good resistance to compressive forces.

These and various other objects and advantages will be readily understood from the following description taken in connection with the accompanying drawings of certain preferred embodiments of the invention, it being understood that the herein description and drawings are set forth for illustrative purposes only, and that modifications may be made therefrom: 1

In the drawings:

Fig. 13 is a fragmentary elevation, partly in cross-section, of a modiiled sheet metal and fiber board container illustrating an alternate embodiment of my invention;-

Flg. 14 is an elevation of a container illustrating an alternate form of my invention and showing a rolling strip;

Fig, 15 is a fragmentary perspective of a modifled bottom with a liner for one of my containers with slits 30 shown in a staggered relation;

Fig. 16 illustrates in fragmentary cross section, a multiply wall of material having an inner liner;

-' Fig. 17 is a fragmentary section of an end portion of a container made in accordance with my invention, which end portion is provided witha special-stiilening ring;

Fig. 18 is a plan view of the stock from which the end portions of the containers are blanked, and shows the corners which remain, which corners may be utilized as support portions for the bottoms of the containers.

Referring to the figures, in which common .parts are designated by common identifying numerals, and referring particularly to Figs. 1-4, it represents a container havlnga cylindrical body" and bottom and top portions IQ and I8 respectively.

As illustrated, container It may have threedistinct piles of fiber board, indi- 18,20 and 22, both in the cylindrical I2an'din the bottom and top portions It Asbest' shown in Fig. 3, the overlapping ends of'plies I2, 20 and 22 are interleaved in order to minimize the overlap joint, and so that top and bottom portions l2 and It may seat tightly within cylindrical bdy portion l2. If desired, a strip 24 of asphalt base tape, or the like, may be interposed at the overlap of plies i8, 20 and 22. which tape may be'thermo-plastic in nature, so that when the top row of stitching as at 25 and 21 is stitched to unite the overlapping Plies, the overlapping plies may be ironed in such fashion that the asphalt base tape tends to definitely flll in the holes caused by the stitching needles in the fiber board.

As.indicated clearly in Figs. 1 and 2, the bottom portion It has a depending flange 26 and the top portion has an upstanding flange 28, which, it'will be recognized by those skilled in the trade, may be provided by a series of radial slits indicated generally as 3E, or by other means of diecutting and scoring therein. As indicated, after the cylindrical body i2 is formed upon a forming mandrel and its plies interleaved as indicated, the plies are stitched into place as clearly indicated preferably by top rows of stitching 32 and 3d.

Thetop It of the container will be provided with'an orifice 38 and after the container is filled,

a conventional expanded metal cover may be fitted therein, as indicated at l8.

The sewn seams may be dipped preferablyin paramn, asindicated generally by the numeral 49.

As a support 2 for the center of the container, a series of plies u of fiberboard, preferably generally triangular scrap pieces 00, suchas are indicated as left from a square piece 01' board (Fig. 18) after the top portions are blanked out therefrom, will be utilized to build up a platform, equal in thickness to the extent of depending flange 20, of bottom portion Id.

As particularly shown in Fig. 4, the stitching l2 and N of top portion It may be cut, and as the container is emptied, top portion I! may be pressed downwardly to follow the material, because top portion it is friction fitted into cylindrical body l2.

Referring particularly to Figs. 5, 8, 7, 8, 9, 10, 11 and 12, the container 48 here illustrated is generally similar to that illustrated in Figs. 1-4; however. a special cover arrangement identified generally as It and heavy strengthening boards 82 and It are provided at the bottom and top oi the container respectively, as indicated.

These strengthening boards may be of heavy wood, thick flber board, or even metal, and will generally be stapled by staples 88 respectively to the bottom It in the top It.

8 0 Top board 5% willordinarily have a square hole 88 cut therein as indicated particularly in Fig. l, and the cut-out may be used as'cover member 69.

When hole 36 is cut in top end member It, the cut-outs are saved and utilized as bottom plies 85 82 in cover arrangement, and will be prefer- .ably stapled as indicated to member to. It will be realized that the plies 62 tightly flt into and friction flt preferably, circular opening 38 in top member it. 40 The cover arrangement W may be held in place by wires, the ends of which indicated as 68 may be stapled through end member i6. If desired, all four corners of the square cover arrangement may be so, wired in place tightly, by twisting 1 the wire 86 as indicated in 88; or alternatively, one corner of cover arrangement 50 may be stapled into place as at I0 and the top member scored as indicated at 12, thus allowing the member ill, after the wires 68 have been removed, to hinge upwardly and downwardly, as'illus'trated in 82. It will be realized that cover member it may have its stitching cut (or pulled ifa chain stitch is utilized) and that the top member It may be pressed downwardly into the bottom of the container.

An important part of my invention is the radial slittings 30 in the upstanding flange 28 of top portion l8, inasmuch as this construction in multiply flanged tops, gives an excellent friction flt, and the flange 28 ,will ordinarily be formed to tension against the cylindrical body portion l2, giving an excellent tight fit.

As indicated, in Fig. 13, the cylindrical body portion maybe formed with one inner ply is or fiber board (one ply or more if desired) and an outer ply of light corrugated metal 16 which inner and outer plies M and it may be sewn together by two rows of stitching I8 and so, which stitching will, at the same time, hold the usual bot- 70 toms and tops id and 16 respectively of the container in place. These bottoms and tops may be similar to the bottoms and tops illustrated in Figs.

1-12 or may be metal-covered if desired. Also,

a seriesof check blocks indicated as 22 may be utilized, if desired, to prevent the top portion 16 Fig. illustrates a bottom member ll for that I type of container illustrated in Figs. 1-12 having additionally thereupon, a liner 86 of any desired material, such as, for example, Pliofiim or other filming material or resinous coating etc. which liner completely covers the center portion of M and the depending fiange 86, also this figure illustrates a definitely preferred form of bottom or top wherein the marginal slits of the three plies of fiber board are staggered, thus preventing leaking tendencies. v

Fig. 16 in fragmentary cross-section, illustrates the inner ply 18 of the cylindrical body portion II of that class of container illustrated in Figs. 1-12, with the addition of an inner liner 88 which completely covers the inside of the container and additionally has turn-back portion 90 so as to cover the raw edge indicated as 92, of ply l8.

Fig. 1'7 illustrates in fragmentary cross-section that class of container illustrated in Figs. 1-12 with the addition of a circular interior stiffening collar 94 which may be stapled as indicatedat'96 both to the plies of cylindrical body I! and to the upstanding fiange 28 of top portion It.

By the above described arrangements, a strong light container is obtained, preferably with a plurality of plies of material; various shapes may be employed, barrel-like or box-like, etc.; the stitching preferably will be of strong cotton thread in a lock stitch, although chain stitching may be utilized and of course linen or even metal stitching may be used; the cotton thread is particularly strong.

Those skilled in the art will recognize the peculiar strength advantage in uniting the plies only at the stitch lines; the individual plies give" separately with the result that sudden impacts and shocks in restricted areas are resisted much more eiilciently than if the plies were joined together in a solid body mass by adhesives or the like. My containers compare favorably with containers formed of light steel or heavy wood.

Various fibre-boards may be used, and like boards or equivalents may be substituted. Fibreboard up to 1%" maybe easily formed on a forming mandrel to give a. cylindrical body; heavier boards are difilcult, if not impossible, to handle speedily and efilciently.

It will be realized that simple tools and dies may be utilized to produce various sizes and shapes of containers embodying my invention.

Inasmuch as my invention may be utilized in part or in whole, and in variant forms in contrast to the illustrativeembodiments above described,

' and with various equivalent structures, in part or in whole, reference should be had to the appended claims'for a definition of my invention; the key essence of which is a cheap light strong container quickly and easily assembled by modernproduction methods.
